“…PIM is made from a solution containing a carrier compound, plasticizer and polyvinyl chloride (PVC) as a matrix polymer that forms a thin, stable and flexible film. The existence of the matrix polymer membrane is expected to overcome the carrier leakage and the presence of plasticizer can stabilize the membrane system [5,[10][11][12]. Transport process of target compounds from source phase to stripping phase in PIM can be explained in three consecutive steps.…”

“…Whereas the use of PILMs had been reviewed in the literature [101] , a new approach to improve membrane performance had been published recently [102] . In this work, PILMs consisted in a mixture of cellulose triacetate, 2-nitrophenyl octyl ether and the macrocycle undecyl-aza-18-crown-6 as carrier.…”

The generation of liquid effluents containing organic and inorganic residues from industries present a potential hazardousness for environment and human health, being mandatory the elimination of these pollutants from the respective solutions containing them. In order to achieve this goal, several techniques are being used and among them, supported liquid membranes technologies are showing their potential for their application in the removal of metals contained in liquid effluents. Supported liquid membranes are a combination between conventional polymeric membranes and solvent extraction. Several configurations are used: flat-sheet supported liquid membranes, spiral wounds and hollow fiber modules. In order to improve their effectiveness, smart operations have been developed: non-dispersive solvent extraction, non-dispersive solvent extraction with strip phase dispersion and hollow fiber renewal liquid membrane. This paper overviewed some of these supported liquid membranes technologies and their applications to the treatment of metal-bearing liquid effluents. KeywordsSupported liquid membranes; Metals; Extractants; Ionic liquids; liquid effluents; Environment. Tecnologías de membranas líquidas soportadas en la eliminación de metales de efluentes líquidos ResumenLa generación, por parte de las industrias, de efluentes líquidos conteniendo sustancias orgánicas e inorgánicas, es un peligro potencial tanto para los humanos como para el medio ambiente, siendo necesaria la eliminación de estos elementos tóxicos de las disoluciones que los contienen. Para conseguir este fin, se están aplicando diversas técni-cas y entre ellas las tecnologías de membranas líquidas soportadas, están demostrando sus aptitudes para la eliminación de metales contenidos en efluentes líquidos. Las membranas líquidas soportadas, resultan de la unión de las membranas poliméricas y de la tecnología de extracción líquido-líquido. Este tipo de membranas se pueden utilizar en diversas configuraciones: plana, módulo en fibra hueca y módulo en espiral y para aumentar su efectividad se están desarrollando las llamadas operaciones avanzadas: extracción no dispersiva, extracción no dispersiva con dispersión de la fase de reextracción y empleo del módulo de fibra hueca, con renovación de la membrana líquida. En este trabajo se revisan estas operaciones de membranas líquidas soportadas y algunas de las aplicaciones de las mismas, en el tratamiento de efluentes líquidos conteniendo metales. Palabras claveMembranas líquidas soportadas; Metales; Agentes de extracción; Líquidos iónicos; Efluentes líquidos; Medio ambiente.

“…Recently facilitated transport of metal ions through polymeric inclusion membrane (PIM) carrier membranes resulted good selectivity in ion separations with real improvement of the membrane stability as compared to liquid membrane [6][7]. Polymer inclusion membranes (PIMs) are becoming of great interest for the separation of chemical species [8][9][10][11][12][13][14][15]. PIMs are thin and flexible films that are easily prepared by casting an organic solution containing a base-polymer, such as poly(vinyl chloride) (PVC) or cellulose triacetate (CTA), an extractant as a carrier, and often a plasticizer or modifier.…”

A study of phenol transport was conducted in correlation to the evaluation of copoly (eugenol-divinylbenzene, DVB) as carrier using polymer inclusion membrane (PIM) method. The performance of copoly (eugenol-DVB) ABSTRAK Telah dilakukan penelitian tentang transpor fenol yang berkaitan dengan evaluasi kopoly(eugenoldivinilbenzena, DVB) sebagai senyawa pembawa (carrier) menggunakan metode polymer inclusion membrane (PIM). Pada tulisan ini kopoly(eugenol-DVB) 12% diobservasi berdasarkan pada parameter membrane liquid (ML) loss. Beberapa variasi, termasuk pengaruh konsentrasi plasticizer, kecepatan pengadukan, dan pengukuran waktu hidup (lifetime) membran telah diteliti. Berkaitan dengan waktu hidup, juga telah dipelajari pengaruh konsentrasi garam NaNO 3 . Tensile strength (kuat tarik) membran sebelum dan sesudah transpor diukur dan dikarakterisasi menggunakan SEM (Scanning Electron Microscope
